<3>When there's a risk of an area code running out of phone numbers, an 'Overlay Area Code' is created that has the same geographic boundaries as the existing area code. In this case, the 707 code has been Overlayed with the 369 area code. New phone numbers in the Duncans Mills area will be assigned with one of these codes: 707 or 369.

The boundaries of the ZIP Code can be changed, re-assigned, eliminated or overlapped with other ZIP Codes.
